Setting fan 1 for temperature intervals
-
Hi
I've read this https://www.duet3d.com/wiki/Connecting_and_configuring_fans and also the info from the reprapwiki. But still I did not understand how can I make my heatsink fan to be controlled in intervals. What I mean about this is that for example, I want to run P1 fan with S0.5 over 60 degrees, S0.7 over 150 and S1 over 200.
Thanks! -
See https://duet3d.com/wiki/G-code#M106:_Fan_On. Sounds like you want L0.5 and T60:200 in the M106 command.

If I insert this I can hear a sound from the fan but it's not spining. Even if I try to give it a push. Same thing for L0.8. It's spinning only if I place L1

Not all fans work with PWM. Have you tried a higher blip time (the B parameter)? You could also try a different PWM frequency (the F parameter). I think the default is 250 so setting it lower might help - say F125 or less.

I buy e3d v6 originals from e3d. So I don't know but from my tests…. their fans don t work in PWM mode.

I too have found that the 30mm E3D heatsink fans don't work in PWM mode.

Have you tried silly low PWM values - like 10Hz? I have a pair of tiny 30mm blower fans that I use for print cooling and use them in PWM mode but had to go right down to 10 Hz but they do work at that.

Yes they work at extremely low PWM frequencies at some PWm values, but not smoothly because of the low PWM frequency. I think the reason is that they don't start up until power has been applied for a certain length of time.
